亚米级影像正射纠正方法研究

Research on the Methods of Ortho-rectification of Sub-meter Images

亚米级的高分辨率影像指的是地面分辨率能达到1 m以下的卫星遥感影像。亚米级影像是省级地理信息资源建设与更新的重要基础性数据。本文依托黑龙江省基础测绘项目,基于PCI软件,以控制点库数据为参考,制定了一套较为完整的从空三加密到正射纠正的亚米级影像制作的技术流程,为推进省级基础地理信息数据快速更新提供了一定的参考。

High resolution sub-meter images refers to remote sensing satellite images of which the ground resolution is less than 1 m.Sub-meter image is an important basic data for the construction and updating of provincial geographic information resources.Supported by the basic surveying and mapping project of Heilongjiang Province,this paper developed a kind of relatively complete technical route of sub-meter images production from aero triangulation to ortho-rectification,based on PCI software and database of GCPs,which is able to provide certain reference for promoting updating frequency of provincial basic geographic information data.
